This is a weird bug that I was hoping Apple had worked on between the release master last week and the official yesterday. It’s stopped me using Notes and Reminders.
It’s like there’s some debug code still enabled but if you watch my video you’ll see a flash of bright light before the app fully opens. I get it with Apple apps including Reminders, Notes and Safari.
It’s very strange given this wasn’t in any previous beta. Just me? (I’m on the iPhone 13 Mini).
I’m going to stay on iOS 15.7 I think to get around this.
